TR6 wider tires

Share this page

I run 205/55 on stock TR6 rims. Speedo calibration is off, ground clearance is less, but no other problems. On a TR6, I'm sure you could find a taller profile, but I actually like the reduced clearance (and taller tires have fitment problems on my TR3).
 
Downside is the steering will feel a little heavier at slow speeds.

Cheers,
Tush
 
For a while I was autocrossing a TR6 when it was classified in E Stock and ran 205/50-15 tires on stock TR6 wheels with no problem. I did a couple of test fits with both 225 and then 215 section width tires on the stock wheels. Based on those test fits, I would not recommend going to any section width greater than 205 regardless of the aspect ratio with the stock TR6 wheels. Since I was also thinking in terms of going to D Street Prepared (bear in mind this was many, many years ago and the car has been reclassified as well as class names have changed) so I also tried some 6" wide wheels and 7" wide wheels and decided that the 6" could just about handle a 215 but still not something I would do. To go to a 225, you really need to think in terms of a 7" wide wheel at a minimum.
 
I'm running 205/70 R15 on my 6 with stock rims.

Unless you raise the air pressure a bit. Up around 30-34 psi (which I'm sure varies from tire to tire and car to car so do your own research) I find that traction and handling improve, while steering effort is less than with skinny tires at the stock inflation.

PS, speaking of higher tire pressures, Mad Marx just mentioned that he picked up 5 seconds in the second race, by raising tire pressure above that recommended by the tire maker. YMMV :smile:

 
My opinion, if you have a stock suspension and you put on wider tires and take advantage of the increased grip it won't be much fun. Without front and rear sway bars and maybe stiffer springs too, you will run out of suspension travel as the body rolls before you will run out of grip, leading to less than optimal handling. I have 205s on my TR250, but I also have the suspension mods.

It is more fun to slip around on skinny tires than lurch around on fat, sticky ones. That said if you like the look or feel better tires are available in the wider widths (probably true) then those might make more sense for you.
 
You raise some excellent points that I had not considered.....they just look SOOO skinny

Whatever tires you install, you'll get used to them in short order and the feeling will be normal.
